"Head coach Phillip Cocu has had it pulling opponent’s jerseys, which already caused 3 penalties and unnecessary goals for the wrong party," the filmer said.

"Cocu has used a renown method of learning defenders to not use their hands, making them hold a tennis ball in each hand during serious training sessions."

"This should help them kick the habit and learn new ways to defend strikers without causing danger for the rest of the team," they added.
